Project File continuously reduces itself

Nobody can operate in thin air and most people around here are just volunteers trying to figure things out. Our telepathic powers only go so far. Without any specific info even the Adobe engineers couldn't answer your question, so for what it's worth, give us something we can work with.

Not sure why Adobe needs to know everything about my machine when this is clearly something that the program is doing. It is simply reducing the project when I am not asking it to do so. It has not done it for years on the same machine, now it does. It also keeps the files I am using, so no issue with the files.

Without exact info about your system, the project, the footage types, where the files are stored and even things like hardware acceleration settings nobody can tell you anything. You need to be much more specific.
